Just saw one like this on the news the other day. A local guy here made his with a snow blower instead of a plow. Makes more sense as you don’t need the heavy torque motors to push a lot of snow, just throw it out of the way.

Nice tutorial, just one small thing I would like to point out.
In the Section about reading resistance you state:

well then you’ve got a 9.90k Ohm (?) resistor (remember you are in the 20k? mode, so the 9.90 has three zeros behind it or 9,900 Ohms)
[/quote]
This is a bit confusing, as adding 3 zeros to 9.90 would be 9.90000, which to some people is still 9.9 ohms. To be more accurate what I think you should say is that you should “move the decimal 3 spots to the right.” Then 9.9 clearly becomes 9900.
